The near-infrared electronic emission spectrum of ScN has been observed in the 1.6-1.8 ,um spectral region using a Fourier transform spectrometer. The three bands with origins at 5820.0944 (5) , 6051.2858(20), and 6266.1290( 13) cm-' have been assigned as the O-O, l-l, and 2-2 bands of the A ix+ -X *2+ electronic transition. The principal equilibrium molecular constants for the ground state obtained from a fit of the observed lines are B : = 0.554 609( 17) cm-', rz = 1.687 23 (3) A and the
